AUTOMATIC RAILROAD-GATE.

Specification of Letters Patent. Patented June 29, 1920.

[Application filed October 15, 1919. Serial No. 330,726.

To all w/wmz't mag concern: I

Be it known that I, Pn'rRo Kim'sz'rorr, a citizen of Ruthenia, residing at Mundare. Province of Alberta, and Dominion of Canada, have invented certain new and useful Improvements in Automatic Railroad- Grates of which the following is a specification.

It is the object of this invention to provide automatically operating railroad gates constructed in such a manner that they will be operated by an approaching train to close a street or road crossing the track and by' the departing train or locomotive to open said street or road and to close the track in order to prevent animals etc., to pass onto the railroad track.

It is a further object of the invention to provide a railroad gateof simple mechanical construction which automatically and positively will close the crossing roadway upon the approach of a train and will open said roadway and close the railroad track by a departing train against the passage of cattle etc., thereon.

The invention consists of the construction and combination of various parts of the mechanism, as will be hereinafter fully described, and then pointed out in the claims. Reference is to be had to the accompanying drawing, forming a part of this specification in which similar letters of reference indicate the corresponding parts in all the figures. I

Figure 1 is a top plan view of my improved railroad gate, and

Fig. 2 is a side view thereof.

The numeral 10 represents the ties, and 11 the rails of a railroad track.

A pair of operating arms 12 are normally extending over the rails and are adapted to be engaged by a suitable operating lever on a locomotive of a passing train.

These arms 12 are secured on pinions 13 and 18, located beside the track, the teeth of which engage with bars 14, and 141 arranged parallel to the track and guided in guide blocks 15 and 15.

These racks 14: and 141 are pivotally secured at their free ends to the ends of draw bars 16 and 16 to the other ends of which links 17 and 17 are pivotally secured.

The barrier bars 18 and 18 are secured to the inner ends of the links 17 so as to normally extend across the railroad track and ciose the same against trespassing animals e c.

Pivoted at the fulcrum point of links 17 and 17 and bars 16 and 16, are the outer ends of rods 19 and 19, the inner ends of which are pivotally secured to one end of links 20, and 20, pivotally secured intermediate theirends to the ties, while other bars and rods 21 are pivotally secured to the free ends of said links; the free ends of which are provided with vertical pins 22 and 22 working in slots 23 and 23 of links 24 and 24; pivotally secured to a tie 10.

' Secured to the outer ends of the bars 21 and 21 are links 25 and 25 to the free ends of which the second pair of bars 25' and 25' forming the barriers are secured so as to normally extend across the track.

Cables 26 and 26 are secured to the outer ends of the links 2 1 and 21 and are guided over pulleys 27 located in suitable guards 28 and are then guided over pulleys 29 and 29 in guards 30 and 30 secured to the horizontal arm 31 of gallows 31.

To the free ends of these cables, weights 32 are fastened which are adapted to slide in a groove of guide posts 33 and which are normally held in elevated position by a hook spring 34 secured to the side of the gallows post 81.

An operating cable 35 is secured to the lower end of the hook spring 3 1 and to an operating lever 36 adapted to normally extend across the rails of a track and to be operated by an operating lever on the departing locomotive.

From the foregoing description it will be clear that the operating lever of a passing locomotive will operate the arms 12 to actuate the draw bars 16 for swinging the barrier bars 18, and by the intermediary of the links and rods 19, 20, 21, and 25 also the barrier bars 25 and 25, to clear the track and to swing to the sides of the same for closing the roadway crossing the track.

, After passing the crossing, the operating arm on the departing locomotive will operate the bar 36 which will tend to pull the spring 34 out of engagement with the weights 32 which then will slide down and exert a pull on the cables 26 and 26 which by the intermediary of the links 24 and their pin and slot connection tend to operate the barrier bars 25 and 25' and by means of the link and lever connection cause the barrier bars 18 to return to their original position as shown in Fig. 1, closing the track against the passing of cattle onto the same.

hat I claim is a l. A railroad crossing of the character described comprising in combination with the bars constituting a double acting barrier, levers adapted to be operated by an operating arm on a locomotive, pinions operated by said levers, racks in mesh with the pinions, and a system of levers adapted to be operated by said racks for swinging said barrier bars out of the way of an oncoming train for closing the crossing against the passage of vehicles and pedestrians, means for normally holding the bars in this position, and means for releasing said holding means by a departing train, for opening the crossing and closing the passage onto the track.

2. A railroad crossing of the character described comprising in combination with the bars constituting a double acting barrier, levers adapted to be operated by an operating arm on a locomotive, pinions, operated by said levers, racks in mesh with said pinions, and a system of levers adapted to be operated by said. racks for swinging said barrier bars out of the way of an oncoming train to close the crossing, Weights connected to said lever system adapted to hold said barriers in their crossing closing position, hooks to hold said weights in their elevated position, means adapted to be operated by a departing train for releasing said weights from said hooks, for returning said barrier bars into their normal track closing position.

In a railroad gate of the character described the combination of a double acting barrier, comprising two pairs of bars, a lever system, weight, means at times for holding said weight in elevated position, means for releasing said weight to operate said lever system for actuating said bars for closing the gate against the passing of cattle onto the track, and means for operating said system to actuate said barrier bars to close the roadway against the track and for elevating said weight substantially as described.

In testimony whereof I have affixed my signature.
